Yes. There's actually a workshop being planned in Yellowknife that's going to be tri-territorial. We're going to be meeting with people from CHARS, Polar Knowledge, and the CMHC, as well as the other jurisdictions, specifically to talk about research gaps and the state of building in each of the three territories. I'm quite looking forward to that.
I just want to pick up on one thing that Mr. Fournier pointed out. I also concur with his approach of using a more passive approach to energy efficiency and doing the basics of good energy-efficient building, which is really important. The other side of that is health. Energy-efficient construction means that, if we create tighter and tighter buildings, but if we don't have good ventilation, we start affecting health. Once again, with all these communities and so many units, one of our big issues in the north is excessive mould buildup in all our units. This is happening, and not just in old units that need upgrading. It's happening in our newer units. Much of it is traced to the ventilation requirement.
We start talking about more efficient HRVs and mechanical ventilation. We've had to put preheat coils onto our units, so they don't freeze up excessively. Also, the air is tempered, so that the comfort level is maintained because some people have been blocking them or turning them off, since they don't like the temperature of the air coming through them. We're actually introducing energy into the HRVs, which is meant to reduce the energy needed for that.
That's what I mean when I talk about a balance in terms of energy efficiency. You can make something based on current materials and technology and keep pushing the envelope to make those numbers go higher and higher, which makes fuel usage go down, technically. However, the livability of the place and the actual operation and maintenance of that place will drastically affect those outcomes, because they're not paper outcomes, but real outcomes. Some of our units have actually seen their energy use not all that different from an older place's, just because of the way it's been used, so we're trying to work on that one as well.
In terms of the usual, most cost-effective, and functional build, the element of health is really important. Just because we put these elements into the build, we also have to sometimes do other things that are counterintuitive to the whole energy aspect. I just wanted to bring that up to understand that we're trying to strike a balance here.
